MEASURING ANI DISFETTSING AEPIRATUS.

Application :filed February 16, 1921,l Serial No. 445,379.

,To all fio/tom t may concern.'

lle it known that l, Lotus BosnNrELD, a citizen of the United States of America, and resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in hieasuring' and Dispensing iipparatus1 of which the Jfollowing is a specilication.

rlhis invention relates to measuring and dispensing apparatus and particularly to a valve controlled `float, and novel means associated therewith for adjustingr the float or setting it in order that it will operate the valve when a predetermined level of liquid is delivered to the receptacle in which the lioat is suspended, the said valve being eli'ective to interrupt the discharge of air 'from within the receptacle and maintain a pressure which will prevent the entrance of additional liquid when a predetermined level is reached.

ik further object ot this invention is to provide a combined float and valve stein, the said stem being adjustable within the valve and effective to support the lloat at ditlerent positions within the receptacle so that when liquid has reached a level to raise the iloat, the valve will be closed.

A still further object of this invention is to provide a tloat and valve stein of the character indicated having graduations which will permit the valve stem to be set for closing the valve when a predeterniined amount of liquid has been delivered to the receptacle.

`With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

ln describing the invention in detail, ret erence will be had to the accompanying' drawings formingpart oi this specification, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a sectional view of a receptacle having a valve contro-lling mechanism embodying the invention applied thereto;

Figure 2 illustrates an enlarged sectional view in detail ot the valve and parts assoeiated therewith; and

Figure 8 illustrates a sectional view on a line corresponding with the line 3 3 of ln these drawings 5 denotes the measuring receptacle having delivery and discharge pipes 6 and 7 respectively, the former otl which admits the fluid to the receptacle and the latter ot' which permits the fluid to discharge from the said receptacle. The discharge pipe has a st ainer or guard 8 associated with it7 which is disclosed in a 'former application, and need not, therefore, be des scribed in detail.

end of the hollow boss and the said sleeve has apertures or vents 16 through which air may be discharged from the interior olf the receptacle.

rllhe valve 14 has a threaded aperture 1T in which the valve stein 18 is threaded for adjustment and the said valve stem supports a tloat 19 through its connection with the tloat as shown in Figure 2 of the drawing. A jam nut 2() is threaded on the. valve stem and is employed Afor engaging the lower end of the valve when the parts have been properly set and it will prove etlertive in preventing' a change ol position of the valve stem when the device is being' operated.

The valve stem has grzulnations 21, the standard o1t which may represent quarts or ,gallons and the valve stem may be properly set with relation to the upper end of the sleeve to denote the capacity of the tank when the float is suspended within the tank at the position indicated by the number of the gradnations.

The cover or closure 1l has its inner sur' face shaped to forni a valve seat 22 with relation to which the valve is movable and hence when the float raises the valve into engagement with the valve seat, the air vente or apertures 16 are sealed and air cannot escape from the receptacle. When such a condition arises, the pressure within thetanlr will prevent the entrance of tluid and the amount of huid indicated by the number exposed on the valve stem will be contained within the receptacle. it such time, the contents of the receptacle may be discharged and the oat will gravitate for a renewal of Utl the operation, and the receptacle may be alternately filled and emptied 'for the delivery of a quantity of fluid indicated.

.In a valve for controlling the displacement of air Within u receptacle, e sleeve slidzlble in un aperture of the receptacle in relation to und operative. with a Valve seat at said aperture, a valve forming zt part of Said Sleeve adapted to coect with the valve seat, means for preventing disassociation of the Sleeve from seid receptacle, a valverstem threaded through the vulve and situated in speced rela-tion to the sleeve, the said sleeve having air discharge orifices at the junction ol the valve und sleeve, and a Heat carried by the valve stern.
